題目:六顆七段顯示器顯示000000~999999,然後從最暗到最亮,6個0是最暗,逐漸亮到6個9,用一個TACT(彈跳開關)去控制0-9% E4 B1 S0 L6 c& K
軟體:MAX+plusII 10.0 M3 C' N! b+ C4 J2 S! T
IC:EPF10K10TC144-4
! \( O) @+ m1 ~5 @' L+ l7 ^' q這是一個朋友的程式,其他功能都已經有了(六顆七段顯示器顯示000000~999999,然後從最暗到最亮,6個0是最暗,逐漸亮到6個9),但他是用CLK" U% U0 E) M# ~+ g8 Q
自動計數(0-9),但是就是沒有辦法用TACT(彈跳開關)去控制0-9,請各位大大幫忙改一下程式!
